There are three categories of automobiles that employ some form of electric and battery powered drive, which we have listed in the table below. As these vehicles need a larger electric motor, they consequently require a larger (higher capacity and higher energy) energy storage device (battery) and as a result achieve better fuel efficiency.

Automobile System Type Com Engine Electric Motor
HEV (Hybrid Electric Vehicle) Large Small
PHEV (Plug In Hybrid Electric Vehicle) Small Mid-size
EV (Electric Vehicle) None Large

Below is a flash animation to simulate the different automobile types and their battery usage. Please click on HEV, EV, or PHEV to view their respective simulation.
